PENGARUH LOKASI BANGUNAN TERHADAP BENTUK DAN KONSTRUKSI RUMAH TRADISIONAL DI JAWA BARAT

Abstract:. West Java has so many topographical area, such as highland (mountain), low land (valley) and coastal area. All of these areas have differently influenced the typology of building system, which coming from their knowledge of local material, cultures, and technology, which have been delivered from their generation. The knowledge has been developed by times with trial and error process and become the local knowledge of this area (specific area). This paper will be elaborating the buildings (houses) on this 3 topographical area, with focusing on 3 systems of the building (house): lower, upper, and middle system. 3 parts of these building have been observed and created to propose the mapping of construction joint system. On this paper, the map of contraction system (which related to the area) has been explored on 3 traditional villages in West Java: Panjalin village at Majalengka District (located at coastal area), Cikondang village at Bandung District (located at highland area), and Mahmud Village at Bandung District (located at lowland area).Abstrak: Jawa Barat mempunyai geografis yang beragam, terdiri dari area pantai, dataran tinggi (pegunungan) dan dataran rendah. Kondisi geografis yang beragam ini, dihuni oleh masyarakat Jawa Barat yang memberikan ciri khas tersendiri dimana kehidupan tersebut berada, khususnya untuk masyarakat perkampungannya. Uniknya di Jawa Barat terdapat berbagai jenis bangunan tradisional yang mencirikan masyarakatnya, misalnya bangunan tradisional masyarakat di pantai, bangunan tradisional masyarakat di dataran rendah, dan bangunan tradisional masyarakat di dataran tinggi (pegunungan). Untuk itu, pada tulisan ini dilakukan pemetaan bangunan tradisional yang mewakili ketiga area tersebut, dengan melakukan pengamatan dan pengukuran bangunan. Pemetaan dilakukan pada 3 (tiga) lokasi yaitu kampung Panjalin–kabupaten Majalengka (yang mewakili area pantai), Kampung Cikondang–Kabupaten Bandung (yang mewakili area dataran tinggi (pegunungan), dan kampung Mahmud–Kabupaten Bandung (yang mewakili area dataran rendah). Setiap area mempunyai keunikan tersendiri, tetapi juga mempunyai persamaan, seperti konfigurasi bangunan, bentuk fisik bangunan, material, dll, tetapi ada juga perbedaan diadalam dimensi dan beberapa detail bangunan.

An assessment of the readiness of construction firms for international construction joint ventures (ICJVs) using the VERDICT model

Purpose The purpose of this study was to assess the readiness of construction companies in Ghana to partner with foreign companies in international construction joint ventures (ICJVs). Design/methodology/approach Using the Verify End-User e-Readiness using a Diagnostic Tool (VERDICT) model, a survey with 31 construction companies was conducted to assess their readiness through four pre-defined elements of readiness. Findings The results indicated the readiness of construction companies to collaborate with potential foreign partners in ICJVs. Notwithstanding, certain areas such as management commitment to change, employee buy-in, process flexibility and technology infrastructure need improvement in some firms to achieve readiness. Government has a role in ensuring the readiness of domestic firms for the international market. Originality/value This study applies the VERDICT model, a tool originally designed to assess construction organizations’ readiness for e-commerce, to assess the readiness of Ghanaian construction companies for ICJVs.

Key drivers for implementing international construction joint ventures (ICJVs): global insights for sustainable growth

PurposeInternational construction joint ventures (ICJVs) are an effective strategy for construction companies worldwide for delivering large and complex projects. Despite numerous ICJVs studies, there is a lack of comprehensive empirical examination of what drives ICJVs implementation. This study aims to investigate the key drivers for implementing ICJVs through an international survey.Design/methodology/approachGrounded on a comprehensive literature review and structured questionnaire survey, 123 ICJV experts' responses from 24 different countries/jurisdictions were analyzed using inferential and descriptive statistics. Mann–Whitney U test was used to determine any divergence of ranking of the drivers by the experts. Factor analysis (FA) was used to identify the clusters underlying the key drivers. Rank agreement analysis was later used to investigate the consensus between experts from developing and developed countries/jurisdictions on their ranking of the clusters.FindingsOut of 34 factors, 26 factors greatly drive the implementation of ICJVs. Mann–Whitney U test results prove the absence of significant disparity among the experts in the ranking of the drivers. Six clusters were obtained through factor analysis (FA), namely, market-penetration and innovation-driven drivers, legal and market-driven drivers, fiscal incentives and market expansion drivers, personal branding drivers, sustainable advantage/power drivers and industrial and organizational promotion drivers. Rank agreement analysis exhibited varied levels of concurrence between professionals from developed and developing countries/jurisdictions.Practical implicationsThe appreciation of the factors motivating ICJVs is beneficial to the successful implementation of ICJV strategies. A clear understanding of the drivers can help practitioners and policymakers to customize their ICJVs to reap the expected benefits.Originality/valueThe study has generated valuable insights into the factors that are greatly driving the implementation of ICJVs worldwide. While the findings of this study provide a profound contribution to theory and practice, it contributes to sustainable growth in different perspectives.

A comparative study on the performance of different types of wallslab connections in liquid containing concrete structures

Waterstops are commonly used at cold joints in construction of liquid containing concrete structures. A common issue with application of waterstops, is their conflict with top layer of slab reinforcements. A common solution is to form an upturn part that raises the waterstop clear of the top slab bars. However, effects of these different types of construction joints on the performance of structures have not been investigated. To that end, full-scale wall-slab specimens, each representing a different type of construction joint, are built and tested under different monotonic and cyclic loadings. The performance of these specimens is compared with regards to first cracking, limit state capacity and leakage. Results of the tests show that conventional flat joint, behaves more rigidly compared to other types of joints. A non-linear finite element analysis of a typical wall-slab specimen, is also presented and its results are compared with the results of the experiments.
